Outline Activities
I have lead a research group exploring materials strength and characterisation in 3D/4D. My research is in the field of deformation, fracture and fatigue on a wide range of structural/functional materials. A major focus is the exploration of the microstructure and the microstructure-property relations of such materials utilizing synchrotron X-ray microtomography at the third generation facilities, in particular the development of advanced 3D/4D measurements of stress/strain, crack-driving forces, chemical composition and crystallographic information in high density together with their applications to various issues in materials and mechanical engineerings. Recently we have proposed a new concept entitled "Reverse 4D Materials Engineering", in which the complex morphologies of existing materials is taken into account to realize a paradigm shift in materials development for structural/functional materials. We are also in charge of the development of new innovative aerospace materials that is based on a real fracture behavior that has been achiebved by applying the above-mentioned techniques.

Educational
Educational Activities
I am teaching three courses on "Strength of Materials" in the bachelor course, which cover basic theories of strength of materials. I am also in charge of student experiments (mechanical testing). In the graduate school, I am teaching a course entitled "Evaluation of structural materials", "Strength of automobiles" and Introduction to automotive science". I also supervise several graduate students, several bachelor students and some pos-docs in the laboratory.
